I am waiting for a reply back from Ian to see if he want me to intervene on behalf of PF as he is a trader on this site.

As he is a trader on this site then the web admin will decide on the next course of action.

If he is banned for treating people like that then he has only himself to blame, in the same way that people are banned for being foul and abusive towards other PF members be they traders, gold members or non gold members.
